Building a new rig, need help

I'm upgrading an ever aging i7 920 system, I'm looking for a considerable upgrade but without breaking the bank. I originally was aiming at 500$CAN, but now I get the idea that it would be a tad low for my needs.

Right off the bat I checked some cpus/prices, and the i5 3570K seem to stand out. Now you're gonna tell me if I'm off or not, I hope it's potent enough to invest for. Before I go further, I'm gonna list you my current rig:

Not sure you need to know, but it gives a perspective to where I'm going to I guess.

Now for the new system, I will keep the GTX560 ti *for now* cuz I just don't have the dough for an upgrade. Well, it's either buy a monster graphic card and no system, or a system and keeping it hehe. I'm not playing alot of games, but I do play World of Warcraft which I've been told is one hungry *cpu* game (more than gpu). I also play Diablo 3, and some car racing games. Those racing games I had to lower the details alot to have a steady 60fps vsync. The aim here is to play near max to ultra details, so you could argue the GTX560 ti has some limitations of its own.

As I said ealier I thought the i5 3570K would make a good upgrade. With that I need:

I'm thinking of buying a Fractal Design Define R4 casing. I really need to specify it, as the side and top fans wholes are by default blocked by dampening material (accoustic stuff). The basic intake comes from a 120mm fan on the front, and the outake is a 140mm fan in the back. If I'm to run stock speeds, do I need an extra fan on top for exhaust? It seems that way the system would be very quiet indeed!

The cpu being about 250$ and the casing around 120$, I don't think I can have a mobo+ram+pw/s for 130$ haha. So realistically I still would like a low number while keeping a potent performance. I understand I'm on an overclocking site, but for the moment I'm gonna aim at stock performances.

Can anyone give me suggestions on the composition of the system? (I'm in Canada, just saying) Thanks!Edited by dIggl3r - 3/11/14 at 3:16pm

Only if you can get a 3570k much cheaper than a 4670k if you're planning to OC either way (4670k is too damn hot OC'd balls to the walls)
One I can think of : Z77X-UD3H
RAM? Why not use your current RAM.

175$ for the motherboard!?!?! My god... I need to cut money somewhere, with taxes and shipping it most not go over 800$. LOL! Also, going 4670, would limit me to the 1150 chipset... which is better or worse than 1155?

Hmm, really thought I would have much more help from you guys, or maybe this isn't the forum I should ask to. You guys know of another site where they could help me better?

I don't know the difference between different chipsets, I'm not even 100% sure which ram to buy (so many numbers, which means what exactly).

I know for sure the casing I'm going to buy, and most probably the cpu, but the rest I got no clue.

This is the right place.
I'll help you out. Get a 3570k and a z77x-ud3h used if you want to fit in your price bracket
RAM : Just get some Kingston HyperX Genesis 1600 or G.Skill ARES/RipjawsX 1600 8GB for either one
PSU : http://www.newegg.com/Product/Product.aspx?Item=N82E16817182263 or Seasonic G650 or CM V650S
Anything else you need? Oh if you want a good heatsink get a deepcool lucifer

Chipset will have minimal impact, save for the fact that Z87 has another intel chip being released for it Z77 Chipset has seen all its cards dealt. So going to haswell could be seen as having "future-proof" merit. (esp if Broadwell features new DDR4 ram )

The ram you require is DDR3, most likely in 2 sticks of 4GB each.

The cpu you buy will dictate which board you buy because of socket, sandy Ivy Bridge Z77 Soc 1155, Haswell+ --> Z87, 1150Edited by Neckbeard13 - 3/12/14 at 6:20pm

Thanks for your input! I got another question:

The casing I chose is optimized for sound (google/youtube it up if you don't know it), as I was saying in my original post, it was the side and 2 top fan wholes "sealed" off by accoustic material, and I was wondering with the stock heatsink, and cpu running at stock speed (3.4GHz... but could easily push to...?), would it get too hot if I was to keep the 2 top exhaust wholes sealed? Would I need to add a second fan in the front intake to compensate? Since the casing is probably the best on the planet sound-wise, if I don't have to open a fan whole, that would be swell.

You're saying the 4670 and the 1150 is future-proof? But there arent DDR4 ram right now, so... I still would have to buy DDR2 *right now*, right?

I read the 4670 consumes more power, so it gets hotter? I'm trying to keep it as cool as possible without having to open one of the 2 top exhaust fan wholes. Also, I'm really trying to save money (as much as possible), if the 4670+mobo > 4570+mobo, I would have to go with least costly.
